There are three different types of films in this presentation:
.mpeg
.mov (quicktime)
.gif

as a rule, try gif first (when available), because in principe, it should work on all platforms and browsers.

1. X-terminals and workstations:
- use xanim for .mpg ou .mpeg films, after saving them on the workstation
- xanim works, but not always, with the .mov films.

2. On Macinstosh/PC:
In principe, all types of films should work, but you must first have told (via the preference menu) your browser where quicktime is.
